Ingredients

I've carefully selected these ingredients to create the ultimate tropical flavor experience. The blue curacao (or spirulina) provides that stunning ocean-blue color, while fresh lime juice balances the sweetness of pineapple juice with bright acidity. Coconut water adds natural hydration and subtle sweetness, and the coconut milk creates that perfect creamy texture without being heavy.

When combined, these ingredients create a balanced mocktail that's refreshing, visually stunning, and transports you straight to the beaches of Hawaii.

2 oz (60ml) Coconut Water: Provides subtle sweetness and hydration without added sugars
1 tablespoon Coconut Milk or Cream of Coconut: Creates creaminess and richness (coconut milk for lighter drinks, cream of coconut for sweeter, richer versions)
1 oz (30ml) Non-Alcoholic Rum (optional): Adds complexity and authentic flavor (Ritual, Lyre's, or Seedlip work well)
Ice: Both for shaking and serving
Garnishes: Pineapple wedges, maraschino cherries, edible flowers, fresh mint

How To Make

Classic Blue Curacao Version:

Pour the blue curaçao syrup, lime juice, pineapple juice, coconut water, coconut milk or cream of coconut, and non-alcoholic rum (if using) into a cocktail shaker.
Add 3-4 ice cubes and shake vigorously for 15-20 seconds until well-chilled.
Fill your serving glass with fresh ice, then strain the blue mixture into the glass.
Garnish with a pineapple wedge, edible flower, or maraschino cherry.
Serve immediately while perfectly chilled.

Blue Spirulina Version:

In a small bowl, mix the blue spirulina powder with 1-2 teaspoons of hot water until mostly dissolved.
Pour this blue mixture into a cocktail shaker along with the lime juice, pineapple juice, coconut water, coconut milk, and non-alcoholic rum (if using).
Add 3-4 ice cubes to the shaker and shake vigorously for 15-20 seconds until everything is well-mixed and chilled.
Fill your serving glass with fresh ice, strain the mocktail into the glass.
Add your favorite tropical garnishes and serve right away for the best flavor and color.

Substitutions

Blue Coloring Alternatives: No blue curaçao or spirulina? Try 2-3 drops of natural blue food coloring or butterfly pea flower tea (which turns blue when mixed with acidic ingredients).
Lime Juice Substitutes: Lemon juice works in a pinch, though it will change the flavor profile slightly. For a less tart version, try ½ oz lime juice mixed with ½ oz simple syrup.
Pineapple Juice Options: If you don't have pineapple juice, try using mango juice or a tropical juice blend. For a less sweet version, dilute with a bit of water.
Coconut Water Replacements: Plain filtered water will work (though you'll lose some flavor), or try using half pineapple juice and half water for a similar effect.
Coconut Milk Alternatives: For dairy-free options, try oat cream or almond milk creamer. Regular half-and-half can work for those who aren't avoiding dairy.
Non-Alcoholic Rum Substitutes: Try a few drops of rum extract mixed with water, or skip entirely and add a dash of vanilla extract for complexity.
Garnish Options: Use what you have! Orange slices, lime wheels, mint leaves, or even a slice of star fruit can make beautiful alternatives to the traditional garnishes.

Pro Tips

Chill Ingredients Beforehand: Cold ingredients maintain flavor intensity and prevent excessive dilution from ice

Fresh Lime Juice Makes a Difference: Always use freshly squeezed lime juice for the brightest flavor

Adjust Sweetness Gradually: Start with less lime juice and add more to taste—finding your perfect balance is key

Coconut Selection Matters: For a lighter drink, use coconut milk; for a sweeter, more dessert-like experience, use cream of coconut

Garnish with Purpose: Edible flowers and fruit aren't just for looks, they add subtle aroma that enhances the drinking experience

Presentation: Serve in clear glassware to showcase the stunning blue color

FAQ

Why is my mocktail not as blue as expected?

Color intensity varies based on the brand of blue curaçao or spirulina used. For deeper color, add an additional ¼ teaspoon of spirulina or extra ½ oz of blue curacao.

Can I make this without coconut products for allergies?

Yes! Substitute coconut water with pineapple juice and replace coconut milk with a splash of oat cream for similar creaminess.

How can I make this mocktail even more special for a celebration?

Create a sugar rim by dipping the glass in lime juice then in blue-tinted sugar, or freeze edible flowers in your ice cubes for a stunning presentation.

Is blue spirulina safe for everyone?

While generally considered safe, pregnant women and those with specific algae allergies should consult their doctor before consuming blue spirulina.

Which version is less sweet?

The blue spirulina version is naturally less sweet. For either version, adjust sweetness by varying the amount of lime juice and coconut milk vs. cream of coconut.

Can kids enjoy this mocktail?

Absolutely! The blue color makes it especially popular with children. Consider reducing the lime juice slightly for kid-friendly palates.

What's the best way to dissolve blue spirulina completely?

Whisk the powder with hot water in a small bowl before adding to other ingredients. The shaking process will help dissolve any remaining small particles.

Can I use a blender instead of a shaker?

Yes, a quick pulse in the blender works well, especially for multiple servings. Just be careful not to over-blend, which can make it too watery.
